Sags and Dips

Play with voltage sags, and see in real-time how your sag affects single-phase and three-phase supplies

Knobs for adjusting power supply parameters, load, source impedance

Real-time display of volts, amps, unregulated voltage, regulated DC

NEW – grab the ends of vectors during voltage sags, and slide them around

Harmonics Primer

An intuitive harmonics simulator

Just adjust the amplitude and phase angle knobs for each harmonic, and immediately see the effect on the waveform

The sliding cursor makes it very clear what we mean when we say “add up the sine waves”

Harmonic Sequences

Fundamental Power Flow

On-screen knobs for dialing in current, voltage, and phase angle

Interact in real time with instantaneous volts, amps, power, power triangle with VA, W, VAR, PF, and more. Drag the waveform cursor left and right to demonstrate that the power waveform is simply the instantaneous voltage waveform multiplied by the instantaneous current waveform

Try dragging around the vertex of the power triangle to see what happens

Symmetrical Components

An animated, interactive way to understand unbalanced three-phase systems, and how positive-sequence and negative-sequence vectors work

Knobs for adjusting amplitude and angle of +, -, and 0 sequence vectors

Real-time effects of vectors, and vector sums

Corresponding sine waves shown as well

Distortion

Knobs let you adjust resistive and inductive impedance

See how distorted currents affect the voltage waveform

Includes resonance, with knobs to adjust resonant frequency and Q

Flicker

Knobs let you control the frequency and amplitude of flicker on your PC display screen

Check out the difference between looking at the screen directly, and watching it with you peripheral vision
